Clemens Ladisch c7f572168f ALSA: usb-audio: add Novation Launchpad support
Add a quirk entry for the Novation Launchpad USB MIDI controller.

QUIRK_MIDI_FASTLANE gets renamed to *_RAW_BYTES because this quirk type
is now shared by different devices.

Daniel Mack 3d8d4dcfd4 ALSA: usb-audio: simplify control interface access
As the control interface is now carried in struct snd_usb_audio, we can
simplify the API a little and also drop the private ctrlif field from
struct usb_mixer_interface.

Also remove a left-over function prototype in pcm.h.

Krzysztof Foltman 4434ade8c9 ALSA: usb-audio: add support for Akai MPD16
The decoding/encoding is based on own reverse-engineering. Both control and
data ports are handled. Writing to control port supports SysEx events only,
as this is the only type of messages that MPD16 recognizes.

Daniel Mack 7b1eda223d ALSA: usb-mixer: factor out quirks
Move all non-standard mixer controls and vendor-specific extensions to a
separate file. Some structs need to be exported now.

Daniel Mack 767d75ad1c ALSA: usb-audio: add support for samplerate setting on v2 devices
Sample rate setting is done with a 4-byte long class request that
addresses the interface.

Clemens Ladisch 015eb0b081 ALSA: usb-audio: use a format bitmask per alternate setting
In preparation for USB audio 2.0 support, change the audioformat
structure so that it uses a bitmask to specify possible formats.

Daniel Mack e5779998bf ALSA: usb-audio: refactor code
Clean up the usb audio driver by factoring out a lot of functions to
separate files. Code for procfs, quirks, urbs, format parsers etc all
got a new home now.

Moved almost all special quirk handling to quirks.c and introduced new
generic functions to handle them, so the exceptions do not pollute the
whole driver.

Renamed usbaudio.c to card.c because this is what it actually does now.
Renamed usbmidi.c to midi.c for namespace clarity.
Removed more things from usbaudio.h.

The non-standard drivers were adopted accordingly.
